摘要
因我国GB50010—2002《混凝土结构设计规范》中尚未列入HRB500级钢筋,《规范》尚未给出HRB500级钢筋混凝土受弯构件的裂缝宽度验算方法。为尽快在我国工程领域推广这种新型钢筋,需对HRB500级钢筋混凝土构件的裂缝宽度进行研究。本文在学习参考国外裂缝宽度控制措施的基础上,探讨了HRB500级钢筋混凝土受弯构件裂缝宽度计算问题。
Because of the method to compute crack width of the members has not been stipulated in the Chinese Design Code ＂Code for Design of Concrete Structures＂ （GB50010--2002）. In order to take the internationalization into reality as soon as possible and popularize this new kind of steel bars in the engineering area in China. It is urgent that the research on crack width of the concrete flexural members reinforced by the HRB500 steel bars . The method to compute crack width of the members will be discussed in this article on the basis of the study of crack width abroad.
